when Calcite will support windowing, like TUMBLE, HOP

["Yuan,Youjun" <yu...@baidu.com>]

Hi all,

I am working on a project to translate SQL into Flink stream API, and want to leverage Calcite to do the parsing, validation and converting to RelNode.
So my question is: is there a plan which release will Calcite support the window functions, as introduced in https://calcite.apache.org/docs/stream.html#tumbling-windows?

I know there are CEIL, FLOOR functions, but that seems not expressive enough to express tumbling, sliding, session window syntax.

Thanks in advance!

We’d like to add these, and there are JIRA cases logged, e.g. https://issues.apache.org/jira/browse/CALCITE-768 <https://issues.apache.org/jira/browse/CALCITE-768>, but we have not committed to a particular timeline.
